This invention aims to provide 'a novel means for propelling vessels,'s1de wheels be-, ing d spensed with, and it being unnecessary to provide a multiplicity of blades, as

-,changes in the'precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of theinvention.

In the drawings 7 Figure 1 shows in side elevation, one of the many ways whereby the device'formingf the subject matter of this application may be mounted on a vessel; Figure 2 is a sec; tional elevation showing the mechanism per se, one of the blades beingin the position which it will assume whilst it is propelling the vessel, and the other of the bladesbeing in an inoperative-position; Figure 3 is a similar view showing the blades as they will appear when in an intermediate or tilt ing position; Figure at is a top plan; Figure 5 is a perspective view showing 'how the blades or buckets are carried by the conveyor chains; Figure Gis a perspective view showing one of the buckets or blades and attendant parts. i V i The device embodies a shaft 1 and a shaft 2, disposed in parallel relation, and supported at 3, in any desired way, on'a vessel l of any description. The-"device may be operated as preferred. In the present em bodiment of the invention,'the shaft 1 has cranks 5 connected by pitmans 6 with theengine of the vessel 4. To the shafts land 2, end and intermediate, sprocket wheels 7 are secured, the sprocket wheels carrying an endless conveyor 8, made up of'chains, each chain including links, and each link comprising. a cup-shaped body 9 adapted to receive a tooth of the sprocket wheel, the

body 9 being supplied at one end, with vspaced'ears l0, and being equipped atits opposite end with an ear 11. ,The body 9 has a projectio n1'2 disposed at Ilgl-l'li angles to the ears IOand 11'. :The ear lit on one link is received between the ears '10 on an ad o1n1ng link, the said ears of ad o1n1ng links-being'connected by a pivot element 1 1. In the projections 12 of the various links are mounted cross ties l7 and- 21, such as rods, the rods extending entirely across, the conveyor 8. The rods 17 and 21 are iglven different numerals, because those rods havedifferent functions. Paddles 22 are pro- Vided, and, ordinarily, no more than two paddlesare used. By means of hinge eyes 23, the paddles 22 are mounted-hingedly on the rods 21. Transverse feet 24 aresecured to the inner edges of the paddles 22 and are sustained from the paddles-by braces 25.

The feet 24 rest on certain of the rods 17 and hold the paddles 22 atTightangles'to the conveyor. When, however, the conveyor moves about the sprocket wheels 7, thepad dles 22 can tilt or feather to some extent,

the result being that the device will act primarily in propelling the vessel, and-not in. lifting a large amount of water needlessly and uselessly,

"Attention is directed mule fact that the I complicatedpaddle wheels in common use aredispens'ed with, and "inthe'ir room is employed the simple'and eifective structure.

shown "in the drawings. The crank connec-c tion shown at 5 -6 is of. peculiar utility-in that it affords the most powerful anddirectf ing means of transferring force from the enginetothe conveyor 8. The device is so constructed that but onev of the paddles will be in the water at a time, and as'one paddle enters the water, the othergpaddle is leaving t a T Purpose of the invention is to create the greatest water propelling forc knownto exist up to thepresent time, and f ly eflicient. The lengthgof the conveyer and .the number of paddles may vary, vbut the structure shown in the drawings carries :out

way;

the device will propel the vessel backwardly with the same power as it propels it for wardly. Although a specific form of paddlehas' been shownat 22, it will be underto apply this" force to all vessels of commerce. The'for'ce is applied to the water in a3 straight"lineparallel to the surface of,

the water, and the device, therefore, is high 100' v What is claimed is In a device of the class. described, a vessel, 'sprocket wheels mounted to rotate on the vessel, sprocket chains comprisinglinks having cup-shaped bodies receiving the teeth of'the sprocket Wheels, the bodies having projections, paddles, means forl mounting f the paddles on the projections of some of the'links ofthe chains for feathering moveinent, rods connecting the) chains and mounted on the projections of the other links thereof, and transverse feetsecured intermediate their ends to the inner edges of the paddles and engaging certain of the *rods to hold the paddles approximately at right anglesto the chains when the paddles are not in featheringposition. 1
